| 【摘要】钢丝绳被广泛运用有各大工程，在起重等重工业设备中更是一种必不可少的部件。钢丝材料的广泛运用主要是因为其在力学性能方面有着巨大的优点：钢丝具有较高的强度，自身重量轻，在工作时能够平稳运行而且不容易突然整根折断因此工作比较可靠。广泛的运用在体现其重要性的同时，钢丝的安全性也与我们大家兮兮相关。因此通过对钢丝在恒应力以及溶液腐蚀情况下其力学性能的研究对安全生产和工作有着重要的意义。33253 本课题设计的对象便是钢丝恒应力腐蚀试验所需要的试验台，试验台研究的对象为直径1mm的钢丝。通过对试验过程的分析，了解到试验台的主要功能便是为钢丝提供一个恒定不变的拉力。从此点要求出发，提出几种试验台的总体结构以及提供拉力方案，从中选取最合理，最方便的的方案进行设计。结合各个细节设计实验台的每个零件，最终装配成符合要求的试验台。试验台的设计要求运用PRE-O软件对个部件的尺寸大小进行设计，每个零件还要求提供CAD三文视图即必要的剖面视图。 由于此钢丝试验台主要用于教学实验，故其设计尺寸不必过于庞大，操作也应当尽量简便。从以上各原则出发，在结合生产实践设计出本文的钢丝恒应力腐蚀试验台。 【毕业论文关键词】钢丝绳、恒应力、pro-e、CAD、设计 Wire constant stress corrosion test bench design 【Abstract】Wire rope is widely used in major projects .In other heavy lifting equipment is an essential component.Extensive use of steel materials mainly because it has a huge advantage in terms of mechanical propertiesThe wire has a high strength, light weight itself.In operation run smoothly and not easily broken and therefore suddenly the whole root work more reliable.Widely used at the same time reflect its importance, security has devastated the wire associated with us.So through the wire and under constant stress corrosion solution study the mechanical properties of the safe production and work of great significance. The object of this project is to test the design of constant stress corrosion test station wire needed,Object Test Bench study for 1mm diameter wire.Based on the experimental analysis of the process, we learned that the main function of the test bed is to provide a constant wire tension.From this point requirements, the proposed overall structure of the test bed and provide some tension programs which select the most reasonable and most convenient solution design. Integration of the various details of the design of each experiment station parts, final assembly into a test bed to meet the requirements. Test rig design requires the use of PRE-O software for size a member of the design, each part also requested CAD three-dimensional view of a cross-sectional view that is necessary. Since this wire test bed is used to teaching experiments, so the design size need not be too large, the operation should be as simple as possible. From the above principle, in the production practice to design wire article constant stress corrosion test station. 【Key words 】wire rope, constant stress, pro-e, CAD, design 目录 第一章 绪论 1 1.1钢丝绳及钢丝恒应力腐蚀试验台的概述 1 1.1.1国外钢丝恒应力腐蚀试验台（拉力试验机）发展情况 1 1.1.2我国钢丝恒应力腐蚀试验台（拉力试验机）发展情况 2 1.2本课题研究内容 2 第二章 试验台方案总体设计 4 2.1钢丝恒应力实验台设计与搭建流程 4 2.2 1mm钢丝力学性能分析 4 2.3试验台拉力加载方案设计 5 第三章 试验台各零件设计 7 3.1传感器选型 7 (责任编辑：qin) |
